Is there is Nvidia WDDM 2.7 driver with working HW scheduling?

    That's what I always do when installing drivers with DDU and it works with any other driver but as soon as internet comes back on, Windows overrides this particular 450 driver.
    I saw that option, I suppose I'll try it then. Any idea what it changes on the system exactly? Could be ExcludeWUDriversInQualityUpdate registry value?
    upd: apparently it changes SearchOrderConfig to 0.

    People still hope for magical tricks to boost performance...

    So has anybody witnessed a mighty boost with this feature?

    No, they don't. The last time I checked their WDDM 2.7 preview drivers still had HAGS disabled and didn't have any control panel (at least in the leaked packages). Nv has it all (all the new features with full installer package including NVCP and the rest) in the form of developer preview or Fast Ring WU downloads.
    AMD has stable WDDM 2.6 drivers like nV and a few WDDM 2.7 beta drivers which are not public (or fully leaked), not on WU and are useless for the likes of us anyway (offer nothing new for the user to play around with).

    Here's the official summary of WDDM 2.7. And still no mention of HAGS either.
    https://docs.microsoft.com/en-us/wi...w-for-windows-10-display-and-graphics-drivers
    And I still don't find anything else public regarding HAGS except from the vague "Reduce latency and improve performance" description that Windows itself has.

    The AMD driver itself is undeniably WDDM 2.7, what individual features it supports is still up in the air.

    So I was technically correct. The best kind of correct

    technically correct is also technically incorrect though.

    Ahh. My bad, 20.5 is indeed WDDM 2.7 already even though HAGS is still blacklisted (at least for Vega).

    Hmm. My screenshots above show HAGS returned to default Off position when I ran an in-place upgrade with the official ISO (just in case because the early upgrade with the UUP->ISO source was wonky on my notebook, so I refreshed all 20H1 installs from the MS ISO yesterday). The drivers didn't change during the refresh upgrades (both were already at place and WU didn't override them).

    Did a clean DDU install of 450.99 just now and yeah it seems to work fine. At least GPUsched is available and doesn't reset after reboots, GPU-Z also reports it as enabled. DCH version.
    Although one weird thing I noticed is I had DDU remove DCH control panel but after driver install I had panel available even with internet disabled. Might be that NVCP is packed with DCH in this case just like Standard.

    Damn, and I thought it was working (if I assume he means "not officially supported" as "not currently functional")! Thank you for forwarding this.

    Ah, good to know.

    I have only just installed the update yesterday, uninstalled the 446.14 driver that automatically installed after updating from 1909,
    then installed 450.99 and the toggle enabled and i restarted as it states.

    Haven't checked if it stayed restarted in my situation yet, but something to check later tonight.

    Edit - it stayed enabled in my case, guess its working!

    Also noticing other issues with build 19041.264 when testing at work, like:

    -Hyper-V adapters being present in device manager (even when removing/restarting) after going through an MDT deployment (even though Hyper-V isn't enabled in the feature list)

    or

    - the logon script we use with people's Active Directory accounts (to connect shared folders when they login) hanging on the step that connects a shared folder on a server still using the SMB1 protocol (yes, the SMB1 feature is enabled with automatic removal too. I've tried to convince my manager to migrate to an environment that supports a higher version, but we apparently still run required software on the server 2003 machine..). Manually running the script after exiting the script prompt works though.

    The real question is whether Hardware GPU Scheduling actually improves performance in today's games. Does it mostly help low-end hardware?

    Yeah that was a strange bug i found, i report it. it only happen a couple of times rebooting. a clean install of 450.99 (Windows Insider Cab) and reboot PC, Hardware-accelerated GPU Scheduling unchecks by it's self. i reinstalling Windows 10 2004 .264 and download 450.99 from https://developer.nvidia.com/directx i don't see that strange bug happening again.

    Note: driver from developer.nvidia.com is around 1.3gb with PhysX but Windows Insider Cab is around 600 mb.

    Do you have Windows Sandbox enabled? On 1909 with WIndows Sandbox I also had Hyper-V network adapter appear in Devmgr when Sandbox was running and it wasn't when Sandbox is closed. But on 2004 adapter is always present regardless of Sandbox running, on top of that if you run and close Sandbox multiple times - more adapters get created like Hyper-V adapter #1, #2, #3 etc and will last until reboot.
    I tried a couple of games and didn't notice any difference whatsoever. I feel like Witcher 3 was running even worse on these drivers but I didn't do any specific benchmarks.
